Eustoma grandiflorum quick seedling-growing method

Abstract

The invention discloses a eustoma grandiflorum quick seedling-growing method. The method comprises the following steps of broadcasting single seed into a deep hole disc, preserving enough moisture and keeping the temperature of the soil at 21 DEG C and ph value of 6.6 to 7.2, supplying sunlight, controlling conditions such as temperature, humidity, PH, EC and illumination during each seedling growth phases and transplating and fixed-planting after 60 days. The soil in the deep hole disc has strong water discharging property; and after seed broadcasting, soil laying can be unnecessary. Eustoma grandiflorum germination rate can be improved to 90% to 95%; germination consistency can be obviously enhanced; seedling growing time can be shortened, so cultivating cost can be greatly reduced; seedling transplantation survival rate can be increased and great post-growth can be achieved; with proper temperature and humidity, seedling diseases can be prevented and seedlings can grow healthily and strongly; the seedlings can grow at low temperature; and lotus throne can be avoided upon bad conditions such as high temperature.

Description

technical field [0001] The invention belongs to the technical field of eustoma planting, and in particular relates to a rapid seedling raising method of eustoma. Background technique [0002] Eustomagrandiflorum, also known as prairie gentian, is native to Nebraska and Texas. Gentian is a steppe gentian plant of the Gentianaceae, which is a one- or two-year herb. Likes warm, humid and sunny. Cold-resistant, not water-resistant. Introduced to Europe and Japan through hybridization and improvement, it has become a seductive and unusual flower. Plant height is 30 to 100 cm. Leaves alternate, broadly elliptic to lanceolate, almost sessile, leaf base slightly clasping; leaf surface blue-green. The stamens are conspicuous, the bracts are narrowly lanceolate, and the petals are imbricate. [0003] Eustoma seeds have higher requirements for controlling conditions such as temperature, humidity, light, PH, EC and water and fertilizer in the seedling-raising stage; the rosette ph...

Problems solved by technology

[0003] Lisianthus seeds have higher requirements for controlling conditions such as temperature, humidity, light, PH, EC and water and fertilizer in the seedling stage; the rosette phenomenon will occur at lower or higher temperatures, resulting in failure to bloom; in the prior art, due to the inability to Well control the conditions required for Eustoma eustoma, resulting in the planting area of ​​Eustoma eustoma is not very large, and it is currently being tried on a small scale. The Chinese patent, the application publication number is: CN103650871A, and the name is: production method of eustoma seedlings, Discloses the production method of the seedlings of Eustoma eustoma, and discloses the relevant production conditions for the production of eustoma seedlings, such as the control conditions of temperature, humidity, light, PH and EC values; the method can improve the germination rate of seeds, reaching 80% %-85%, but this method takes a long time to produce seedlings, so it is necessary to provide a fast and high-quality eustoma seedling raising method
